Bug Description

When following the 'powerdebug' test here [1], powerdebug comes back with this error message:

Unable to find clock tree information at /sys/kernel/debug/clock.n', 'enter',

Amitk's explanation on IRC was:

<amitk> mpoirier: it means that the clock tree on the u8500 isn't exported via /sysfs

Something that was done with commit "763eef8 ux500: add debugfs support for powerdebug", but that code was clobbered somewhere during kernel upgrade/merges because it is no longer there.

Philippe fixed this problem in the kernel and it should be working now.
